Both of them wore frocks with nice slits up the leg to show off their gorgeous gams, so it's pretty obvious that they chose these dresses specifically to complement each other.

But while they both flaunted an equal amount of leg, one of them definitely outdid the other in the boob department.

Yep. You guessed it. Check out Kim's insane cleavage.

Damn. You'd think the shock factor in seeing her breasts out on display would've worn off by now, but for whatever reason, her "girls" still make our jaws drop every single time.

And here's a better shot of Kim and Khloe's lower halves. Honestly, it's a pretty close call as to who has the nicer set of stems.

(On a side note, Khloe definitely wins in the shoe department. Those sandals are all sorts of fab.)

And I guess overall, I'm digging Khloe's look as opposed to Kim's, simply because of the whole "less is more" concept. She looks super sexy and she's showing a tiny bit of cleavage, but she still leaves a little bit up to the imagination.

But while both of them definitely turned heads, I have one burning question on my mind. What the hell is up with the two of them looking so glum? They look like they're headed to a funeral versus an event to promote Keeping Up With the Kardashians, what with how annoyed and depressed their expressions are. Wouldn't they have looked even hotter with smiles on their faces? What a waste of a couple of amazing outfits.

Gah. I guess the two of them attend so many of these things that they simply aren't impressed to hit the red carpet anymore. (Must be nice.)
